FIGURE 28.2: Horizontal bar charts for each OST show the spatial-temporal
pattern of writes in the 12,000 core VPIC run. Writes appear clustered by the
8 distinct timesteps in the output file.
FIGURE 28.3: Box and whisper plots show the distribution of write band-
widths to each OST in the 1,728 core VORPAL run. OST 126 had an abnormal
number of low-bandwidth writes in the B/s and KB/s range.
